| Hydraulic Oil Temperature | AMBER | The hydraulic oil temperature in the HX145LCR is higher than normal, reducing system efficiency. | Reduce load and allow the system to cool; check oil cooler for debris. | |
| Low Fuel | AMBER | Fuel level in the HX145LCR's tank is low and requires refueling soon to avoid air in the system. | Refuel as soon as possible to prevent engine stalling. | |
| Water in Fuel | AMBER | Water has been detected in the HX145LCR's fuel system, which can cause injector damage. | Drain the water separator immediately and check for fuel contamination. | |
| Glow Plug / Preheat | AMBER | The preheat system is active on the HX145LCR; wait for the indicator to turn off before starting. | Turn the key to the on position and wait until the light goes out, then start. | |
| Seat Belt | RED | The driver's seat belt is not fastened on the HX145LCR; operation is not allowed. | Fasten your seat belt immediately to clear the warning. | |
| Parking Brake | RED | The parking brake is engaged on the HX145LCR; disengage before moving. | Release the parking brake before driving. | |
| Swing / Slew Lock | AMBER | The swing lock mechanism is engaged on the HX145LCR, preventing upper structure rotation. | Release the swing lock before operating the swing function. | |
| Work Lights | GREEN | The work lights are turned on for improved visibility on the HX145LCR. | No action needed; indicates active lighting. | |
| Beacon / Rotating Light | GREEN | The rotating beacon is active on the HX145LCR to alert nearby personnel. | No action needed; beacon is functioning. | |
| Air Filter Restriction | AMBER | The air intake filter on the HX145LCR is clogged and needs replacement. | Replace the air filter element at the next service interval. | |
| Fuel Filter / Water Separator | AMBER | The fuel filter or water separator on the HX145LCR requires maintenance or draining. | Drain water or replace the fuel filter as per service schedule. | |
| Service / Hour Meter | AMBER | Scheduled maintenance is due on the HX145LCR based on engine hours. | Perform the required service as outlined in the operator's manual. | |
| DPF / Regeneration | AMBER | The diesel particulate filter on the HX145LCR needs regeneration to clear soot buildup. | Drive at highway speeds or initiate parked regeneration per instructions. | |
| DEF / AdBlue | AMBER | The DEF level in the HX145LCR's aftertreatment system is low or quality is poor. | Refill with fresh DEF to restore emissions compliance. | |
| Overload / Capacity | RED | The HX145LCR has exceeded its rated lifting capacity, risking tip-over or structural damage. | Immediately reduce load to within safe limits. | |
| Low Oil Level | AMBER | Engine oil level in the HX145LCR is below the minimum mark. | Add oil of the specified grade to bring to full level. |

Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Clogged radiator core
- Failed thermostat
What to do
Stop the HX145LCR immediately and allow engine to cool. Check coolant level and add if low, clean the radiator fins with compressed air, and inspect the thermostat; replace if faulty.
Low Oil Pressure
Common causes
- Low engine oil level
- Worn oil pump
- Blocked oil filter
What to do
Shut down the engine on your HX145LCR right away. Check oil level and top up to full, replace the oil filter, and if the light remains, have the oil pump inspected by a Hyundai technician.
Hydraulic System Failure
Common causes
- Hydraulic oil leak
- Failed hydraulic pump
- Contaminated oil
What to do
Stop the HX145LCR and check for visible leaks. Inspect hydraulic oil level and condition; if low, top up and prime system. If pump failure is suspected, contact Hyundai service for replacement.
Battery Discharge
Common causes
- Defective alternator
- Corroded battery terminals
- Parasitic electrical draw
What to do
Check alternator belt tension and wiring on the HX145LCR. Clean battery terminals and test charging voltage. If the light persists, measure parasitic draw and repair as needed.
Frequently Asked Questions
How do I initiate a manual DPF regeneration on the HX145LCR?
Park the machine on a level surface, engage the parking brake, and ensure the engine is at operating temperature. Press and hold the regeneration switch on the dash until the DPF light changes from flashing to solid. The process takes 20-30 minutes; do not interrupt.
What is the recommended hydraulic oil change interval for the HX145LCR?
Hyundai recommends replacing the hydraulic oil every 1000 hours or annually, whichever comes first. Always use the approved oil grade listed in the operator's manual to maintain performance.
Why does the swing lock light stay on even after disengaging?
This can indicate a stuck solenoid or faulty swing lock switch on your HX145LCR. Check the swing lock mechanism for debris and test the switch continuity. If the light remains, consult a Hyundai dealer for electrical diagnosis.
How long should the glow plug light stay on before starting?
Typically 5-10 seconds depending on ambient temperature on the HX145LCR. Wait until the light turns off completely before cranking the engine to ensure proper preheating.
What does the service hour meter light mean?
It indicates that a scheduled maintenance interval (e.g., 250, 500, 1000 hours) has been reached for your HX145LCR. Refer to the maintenance schedule in the manual for the specific services required.
